JOSEPH B. STONE, OF JERSEY CITY, NEW JERSEY,

IMPROVEMENT IN LOCK-HINGES.

\ Specification forming part of Letters Patent No. 198,822, dated January 1, 1878; application filed November 8, 1877. l

To all whom it may concern:

Be it known that I, J osnrn B. STONE, of Jersey City, in the county of Hudson and State of New Jersey, have invented a new and Improved Lock-Hinge, of which the following is a specification:

In the accompanying drawing, Figure 1 represents a top view of my improved'lockhinge; Fig. 2, a sectional side view of the same, shown in locked position; and Fig. 3 is a detail vertical central section of the hinge, with the gravity-catch shown in the act of locking.

Similar letters of reference indicate corresponding parts.

This invention relates to an improved lockhinge for shutters, gates, doors, &c., by which they may be securely and firmly locked into open position by a simple and durable attachment to the hinge; and the invention consists of the novel combination, with a second guide-sleeve of the swinging hinge, section, of a vertically-sliding gravity-catch,

with wedge-shaped end, that passes over andlocks to the fixed pintle-bracket of the hinge,

all as hereinafter more fully described and claimed.

Referring to the drawing, A represents the pintle-section, and B the sleeve-section, of a common hinge, as used for shutters, gates, The pintle-section is applied permanently to the window or other frame, and the sleeve-section strapped or fast ened to the shutter or gate. To the sleevesection Bis cast, welded, or otherwise applied, a second sleeve, 0, back of the main sleeve, and-in line with the supporting-arm of the latter. The second sleeve 0 guides a vertical gravity-catch, D, that may be raised or dropped to a certain extent by means of a center slot of the catch, and a fixed diametrical pin of the sleeve. The lower part of the gravity-catch is beveled off or made wedge-shaped, the beveled-off side passing along the bracketarm of the pintle, when the shutter isopened, so as to be raised thereby until the gravitycatch has passed entirely over the arm and drops at the other side, locking thereby, by the straight rear part, the shutter rigidly in position against the fixed pintle-arm.

The upper part of the gravity-catch. is made in the shape of a button, so as to be readily taken hold of for raising the catch and admitting its clearing the pintle-arm when it is desired to close the shutter or gate. In this manner a simple gravity-catch, worked in con nection with the lower hinge, secures the looking of a shutter or gate in reliable manner without any spring, drop, or other catches that require a separate attachment to the wall or other place.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- In a lock-hinge, the combin ation with pintle and sleeve, of an auxiliary sleeve, 0, having cross-pin, and a vertically-sliding slotted gravity-catch, D, beveled at the lower part, as shown and described.
